Use Android Number Keypad but allow negative numbers

Question

I have an EditText field that I would like to only enter negative or positive numbers.

When I use InputType.TYPE_NUMBER it will bring up the nice numeric keyboard which is what I want; however it will only let you enter positive numbers even though the negative button is on the numeric keyboard.

I tried using the InputType.TYPE_NUMBER_FLAG_SIGNED and it will allow the user to enter negative or positive numbers like I want; however it brings up the standard alphabetic keyboard.

Is there anyway to bring up the numeric keyboard and allow negative numbers?

Any help with this would be greatly appreciated.

Answer 1

android:inputType ="numbersigned"

This works for me.

Answer 2

for your EditText in XML, you can force the input type to number only by using android:inputType XML attribute set to numberSigned, number or numberDecimal. You can also force it via setRawInputType.

You can also force the keypad to show only numbers by setting android:digits XML attribute

Answer 3

Just use android:inputType="number|numberSigned" or in Java setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_SIGNED)
